BEIRUT/JERUSALEM, Sept 24 (Reuters) - An Israeli airstrike on the southern suburbs of Beirut on Tuesday killed a Hezbollah commander who was a leading figure in its rocket division, two security sources in Lebanon said, as fears of a full-fledged war in the Middle East mounted.

Hezbollah senior commander Ali Karaki, who was targeted in Monday’s strike on Beirut, survived the attack, Hezbollah officials said. Two senior Israeli sources confirmed to ABC News that Karaki had been the target of the strike. At least six people were injured Monday in an Israeli strike on southern Beirut, according to Lebanese state media.
